7f1a2be0fe Allow basefee as Yul identifier for EVMVersion < london 
This was done to prevent basefee from being a breaking change. This change will be removed in 0.9.0.

TODO revert this commit in breaking.

011f8d3ff7 Changed the type of gas calculation to bigint instead of size_t 
Since the gas calculation can involve multiplication by ``--optimize-runs``, it is possible that
`size_t` is not enough to represent the total gas.

94f9410abe Added hashFunction to Dialect. For EVMDialect, it is keccak256 
In a later PR, the functions `storageLoadFunction`, `storageStoreFunctions`, etc will be refactored
to return a YulString instead of a pointer to a BuiltinFunction.
